I wonder ....

Is there are library of math functions available that one could use an "include 
file" to point to math functions as needed? 

Does such a library exist for HLBL ?

It's not built-in. You have to code it the hardware - a loop multiply.

Hi List
    Does anyone know how to do a power function x^y in HLBL?

    Similar to the pow(x,y) call under C

    or CALCA block EXP x y



Thank you,
